一、区域地质及地层简况本煤田属早第三纪全隐蔽式煤田,为一北东东走向的南陡北缓的宽缓含煤盆地。煤田内及外围出露的地层有新生界、元古界及太古界。从新到老简述如下(见综合柱状图)。第四系(Q):覆盖着整个煤田,厚度7.5～42.0米,由砂质粘土、泥质砂土及砂砾层组成,砂质粘土中常含有钙质结核,砂层和砂砾层层位和厚度均不稳定。与下伏地层新第三系呈不整合接触。
First, the regional geology and stratigraphic profile The coalfield is an early Tertiary all concealed coal, as a north-east eastward slow north wide gentle coal basin. Stratum exposed in and around the coalfield are Cenozoic, Proterozoic and Archean. From new to old briefly as follows (see the integrated histogram). Quaternary (Q): covering the entire coal field, with a thickness of 7.5-42.0 m. It is composed of sandy clay, muddy sand and gravel layers. Calcareous nodules, sandy and gravel layers and thickness Are not stable. Unconformity with the Neogene of the underlying strata.
